Hi I’m downloading temperature and RH data of my PA-II sensor. I find the data downloaded (temperature and relative humidity) from API are very different to the data displayed on the PA map (estimated temperature and RH).

Anyone knows if the web-based data have some correction built into it? As they seems to match better with the readings from thermal couple. Thanks
